An embodiment method of network node operation includes indicating, by a first network node, to a first UE, a first number of REs in a first set of RBs for a first reference signal, transmitting, by the first network node, to the first UE, the first reference signal in accordance with the first number of REs and a first precoding in a first subframe, receiving, by the first network node, from the first UE, a report indicating a first MCS in accordance with a level of signal and interference measured by the first UE, wherein the measurement is restricted to the first reference signal, and transmitting, by the first network node, a first data with the indicated first MCS and the first precoding in a second subframe, the first data being transmitted on a second number of REs in the first set of RBs in the second subframe.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The method of claim 1, wherein the report comprises the CQI, a CSI resource indicator (CRI), and a rank indicator (RI).
3. The method of claim 1, wherein the interference measurement is on at least the NZP resource(s) configured for the interference measurements, and wherein the interference measurement is further on CSI interference measurement (CSI-IM) resource(s).
4. The method of claim 1, wherein the interference measurement is on at least the NZP resource(s) configured for the interference measurements, and wherein the NZP resource(s) configured for the interference measurements include second NZP CSI-RS resource(s) that are different than the first NZP CSI-RS resource(s).
7. The method of claim 2, wherein the RI indicates a rank for a number of layers/ports associated with the first NZP CSI-RS resource(s).
8. The method of claim 2, wherein the RI indicates a rank equal to a number of selected layers/ports within the first NZP CSI-RS resource(s).
9. The method of claim 1, wherein the first NZP CSI-RS resource(s) consist of a single NZP CSI-RS resource.
10. The method of claim 1, wherein first NZP CSI-RS resource(s) include multiple NZP CSI-RS resources.
15. The method of claim 14, wherein the interference measurement is on the NZP resource(s) configured for the interference measurements, and wherein the interference measurement is further on CSI interference measurement (CSI-IM) resource(s).
19. The UE of claim 11, wherein the report comprises the CQI, a CSI resource indicator (CRI), and a rank indicator (RI).
20. The network device of claim 13, wherein the report comprises the CQI, a CSI resource indicator (CRI), and a rank indicator (RI).
